Bit Face Shape Selection:

1. Drop Center Bit

Maximize penetration in soft to medium-hard, fissured rocks. Suitable for low to medium air pressures while ensuring optimal hole deviation control.

2. Concave Face

The versatile choice for medium-hard, homogeneous rocks with excellent hole deviation control and superior flushing capacity.

3. Convex Face

Achieve high penetration in soft to medium-hard formations with low to medium air pressures. Offers remarkable resistance to steel wash, reducing gauge button wear, although with reduced hole deviation control.

4. Flat Face

Ideal for hard to extremely hard, abrasive rocks in high air pressure applications. Offers impressive penetration rates and resistance to steel wash.

 Raw Material

Steel:

Utilizes first-class special alloy steel known for its exceptional strength, heat resistance, and wearability.

Carbide
Leverage China’s finest tungsten carbides for outstanding performance.
Access premium tungsten carbide options from Europe.
